Custom Zipper: Brass or Aluminum – How to Choose
Planning your next jacket or luggage production run? One small component can change the whole feel of your product: the zipper.
If you're sourcing zippers for a new line of backpacks, you might be weighing two things: a solid metallic look and keeping the finished item lightweight. Or maybe you're designing jeans and need a classic metal zipper that can handle daily wear. That's where the choice between brass and aluminum zippers becomes important.
Brass zippers are made from a brass alloy that gives them a premium metallic texture. They're often used in leather bags, jeans, outdoor luggage, and premium apparel. Brass also provides strong tensile strength, making it a reliable choice for products that get opened and closed often. If you want a traditional, slightly heavier feel, brass is a solid direction.
Aluminum alloy zippers are built for a different set of priorities. They are about 35–50% lighter than brass zippers, which helps reduce the total weight of luggage and outdoor gear. They still slide smoothly and come in finishes like bright silver, matte silver, black, and champagne anodizing. Aluminum zippers are commonly used for hard luggage, backpacks, and sportswear, where every gram counts.
Both types are available in different tooth styles: Y teeth, Corn teeth, Euro teeth, and Normal teeth. And both can be made in sizes #3, #5, and #8, with custom sliders and pullers for OEM and ODM projects.
At YAB ZIPPER (Wenzhou Runhe Garment Accessories Co., Ltd.), we produce both brass and aluminum zippers in-house, with over 30 years of experience in the zipper industry. Our team can help you match the right metal and finish to your application—whether it's a luxury handbag, a rugged suitcase, or your latest activewear drop.

So before you place your next custom zipper order, think about what your product really needs: a heavier, classic feel with high strength, or a lightweight solution that keeps the design sleek? The right zipper should solve a problem, not create one.
